Re: [ft-devel] Cleaning up include paths

I have wanted to reply to this, but proper reply is very lengthy so it has
been sitting in my inbox.  And now I truly regret not having replied before
you made the release.

This is actually more problematic. :(  Basically you have undone what I was
suggesting.  What I was suggesting was to move ft2build.h out of /usr/include
exactly so all freetype headers will be in a freetype-private include dir
(/usr/include/freetype2).  It's the "private" part in that sentence that is
key.  It would make sure that freetype headers will be picked up exactly from
where the pkg-config file says, not from whatever prefix happens to be first
in the header search order.  Does it make sense?
